    Abstract: A makeup liquid container with an applicator includes: a container body 1 having a barrel portion 8 and an open neck portion 6; a cap 4 designed to be screwed to the open neck portion 6 of the container body 1; a squeezing sleeve 3 fitted in the open neck portion 6 of the container body 1; and an applicator shaft 5 extended downward from the cap 4 into the container body 1 through the squeezing sleeve 3. A stirrer 9,91 is rotatably disposed in the barrel portion 8 in sliding contact with the inner surface of the barrel portion 8. An engaging device provides a driving connection between the cap 4 and the stirrer 9,91 in such a manner that the stirrer 9,91 is rotated when the cap 4 is rotated in the screwing and/or unscrewing direction and that the driving connection between the cap 4 and the stirrer 9,91 is dismissed when the applicator shaft 5 is extracted from the container body 1.

  • Patent number: 4657161
    Abstract: A dispensing container for cream-like fluids includes a cylindrical body having upper and lower closures. The lower closure is a piston which moves toward the upper closure as the fluid is dispensed from the container. Normally, the container is filled with fluid and then closed with the lower closure. The lower closure or piston is provided with a hole which permits air between the fluid and piston to escape when the lower piston is mounted in the container. The hole is sealed with a disc located at the lower inside portion of the container. The container can advantageously and rapidly reduce the quantity of air remaining in the container thereby reducing deterioration of the fluid due to contact with air.
